scripts.
There's two approaches. You can do this:
% cat setup-script
#!/bin/sh -f
...
exec $SHELL
%
Or this:
% cat setup-source.tcsh
set noglob
eval `setup-script`
unset noglob
%
If you do this a lot, writing a small "dump-env" program to stick on
the tail of setup-script to make it automagically painless is an
obvious step. It's not even that hard to end the setup-script with
something like:
if [ $# -gt 0 ]
then exec "$@"
else dump-env CC CFLAGS FOOFLAGS ZOT BOTTLECAP SQUEAMISH OSSIFRAGE
fi
so it can be used in either context as the user prefers.
You're not writing scripts in English.
Nor do I write scripts in tcsh. Shakespeare did some nice scripting in
English though.
Shakespeare did no such thing. The closest thing I know to scripts in
English are things like Roberts Rules Of Order, statutory law, and
bureaucratic regulations. These examples should make the problem
obvious. Languages used in different contexts have different
requirements.
